Saw a thread describing the same issue;
User cannot (easily) connect to a site with a self-signed certificate.
More or less the same "add exception" comes up as it does when surfing directly to the site, but with the difference that you can ONLY add this exception if you login with the user/pass to the Astaro-box with admin-rights.
This is in one way a "neat" feature to be able to add exceptions on the fly as "admin", but it's not a solution for the users.
